T all whom it may concern."

Be it known that we, GEORGE \V. CASE and JOHN W. ROBERTS, citizens of the Uni-ted States, residing at Passaic, int-he county of Passa-ic and State of New Jersey,'ha;ve invented anew and useful Method of Making Loose-l/Vrapped Folding Boxes, of which the following is a specification.

Our invention relates to anew and useful method. of making loose wrapped folding boxes, and has for its object the application of a covering of loose wrapper to a folding box in such manner that when the box is unfolded and thereafter refolded certain. portions of the wrapper will be transferred from their original positions todi'fferent positions relative ,to the box.

A furtherjobject of our inventionis to use a made up folding box as a form around which to fold the wrapper in such manner that when the box is unfolded the wrapper will unfold therewith so that boththe' box blank and the wrappermay lie flat for ship ment. I

In order that those skilled in the art to which this invention appertains may understand how to use the same we have illustrated the steps of the process in the draw ings forming a part of this invention, in

p which Fig. 1, representsa blank for the-formation of a box of proper folding thereof.

Fig. 2, shows the box'blank after the loose wrapper has been attached thereto.

F ig. .3, is a perspective "showing a folded box placed in position upon the wrapper prior to the latter being folded around said box.

Fig. 4:, is a perspective showing the wrap per being folded around the box.

Fig. 5, shows the box after the wrapper has been completely folded around the same and attached thereto at certain points.

Fig. 6, is an enlarged longitudinal central section'of Fig. 5.

Fig. 7 is a cross section of Fig. 5.

Fig. 8,is abroken away perspective showing one of the inset folds of the wrapper illustrating the manner of forming a bellows fold of that portion of said wrapper lying between the right angle formed by the meeting of the wings.

Heretofore to produce a loose wrapped web sections and'the side box it has been necessary to use a set up or permanently formed box and to enclose the I same in a loose wrapper attaching the edges of said wrapper tothe inside surfaces of the sides and end of'th'e box by adhesive ma .terial and such method precludedthe possibility of utilizing a loose wrapper: upon a folded box. To overcome this difficulty and to provide a method by which a loosew'rzip per could be attached at certain points to a folding box in such manner that the "box may be unfolded. into the original form'of its blank while maintaining the loose wra-pper in proper relative position to the blank thaft whensaid blank is refolded in box'shape por; tions of the wrapper would assume differcut positions relative to the'SectiOnsof the box we place a folding box in its made up shape upon a wrap-perffold,-the wrapper around thisbo-x in its completed shape attaching certain portionsofthe wrapper to certain portions of the box then unfoldmg the box the blank from whichfthe latter i is made will carry with: it the wrapper and then when refolding the box said wrapper will assume the proper position about the box intended for commercial use.

In carrying out this processwe may use any suitable box blank which we have here shown in Fig. '2, a blank especially adapted for use in this connection which blank .con-

sists of a central section 1, side rsection sf 2 said' side sections either being of asinglelayer ofmateria'l as here shown or a double layer as is sometimes used and these side sec: tions hayeend extensions 3 formed therewithwhile the central section also hasthe end sections 4 formed therewith with which latter are formed the .infolding sections 5 terminating in the locking strips 6', such a blank when properly folded will produce the box indicated at 7 in Figs. 3 and 4:, and the first step in our process consist-sin placing this box upon the wrapper 8 s0 that the cen t-ral section 1 of the box will lie upon the central section 9 of the wrapper while the.

second step is the folding of the wrapper around the box so that the side wings 10 thereof will cover the outer surfaces of the side sections of the box, the edges of said wings being turned inward against the inner surface of said side sections and attached there-to by suitable adhesive material as indicated at 11, in Fig. 7

The position of the adhesive material upon the wrapper for this attachingis unit i V thefendsectionsu l and the end wings cated t,12;- During this folding of the wrapper-around the box the triangular sections 13 are folded inward upon the lines 14: I

to form inset folds which during this portion of the-process lie against the outer surface of the end sections 4L of the box while the end wings 15 ofthe wrapper enclose these inset folds the outer edges of said wings bein turned over the upper edges of the ends of the box and attached to the inner surface of the infoldingsections 5, as

, indicated at 16; an adhesive material for this attaching being indicated at 17. r This folding'of the wrapper around the box leaves as a surplus a portion of the wrapper at each corner of the box where the edgesof the side wings and the webs come together and this surplus is taken care of by turning inward to form a bellows fold 18 each of which in the completed box lies inthe inside corner of the box between the end extensions 3 and the infolding sections 5 ;thus when the box is unfolded these bel- --lows folds will beexpanded to permit the blank to lie fiat; I j

After the wrapper has been folded around the box and caused to be attached thereto as above described the next step in our pro cess is the unfolding of the box to cause the inset folds to be withdrawn from between while the next and final step in our process isthe refolding of the box to cause the inset folds to'assume their proper positions between the end extensions 3 and the end sections 4:,as shown'in Fig. 6, this producing a loose wrapped-foldedbo-x ready for commercialuse. a

v While .wehave shown as described a.

particular kind of folding box and a definite form of Wrapper as Well as the process in detail it is not our intention to limit our invention to any form of box or wrapper nor to the minor details of the process as these may be varied within the limits of the appended claims without departing from the spirit of our invention.

VHaving thus fully described our invention the transfer of certain folds in the wrapper loose from one position to another relative to the sections ofthe box.

finally refolding the blanks to cause the insetfolds to assumedifi'erent positions from that in which they were originally folded} x i 3. The process of manufacturingwboxes consisting in' applying a loose wrapper to 'a folding box when the latter isnin its made up form, unfolding the box and refolding the same for thetransfer of certainpor- V tions of said wrapper. from the positions originally assumed to new (positions relative to the sections of 'the box; 4. The process of manufacturing loose wrapped folding boxes consisting of attaching a wrapper to a box when in its folded condition, forming inset folds andpbellows' folds at the vertical corners and transfer ring the inset foldsfrom their original po sitions upon the outside of the box to positions between certain sections of the box.-
